[09:14:08] Customer: Hi, after upgrading my self-hosted photo library last night, the mobile app stopped backing up new photos. Existing photos still appear normally.

[09:14:31] Support: Hi! I can help with that. Which server and mobile app versions are you running?

[09:15:02] Customer: Server is 1.112.1 in Docker, and the Android app is 1.109.0.

[09:15:26] Support: Thanks. The app is older than the server, and that version mismatch can interrupt uploads. Please update the Android app first, then reopen it and check the backup status.

[09:17:43] Customer: Updated to 1.112.1. Backup now says “Waiting for Wi-Fi,” but I’m already connected.

[09:18:11] Support: Please open Backup settings and confirm that “Wi-Fi SSID restriction” is either disabled or includes your current network. Android may report a different SSID if you recently changed routers.

[09:19:06] Customer: That was enabled with my old network name. I disabled it. Now three photos uploaded, but one video keeps failing with HTTP 413.

[09:19:34] Support: A 413 response means the upload exceeds a size limit in your reverse proxy. Are you using Nginx, Caddy, Traefik, or another proxy in front of the server?

[09:19:47] Customer: Nginx Proxy Manager.

[09:20:18] Support: Add the following line to the proxy host’s Advanced configuration, then save it:

client_max_body_size 0;

That removes Nginx’s request-size limit. You may need to restart the proxy container afterward.

[09:22:51] Customer: Done and restarted it. The video is uploading now.

[09:23:09] Support: Great. Once it finishes, verify that it plays in the web interface and that a thumbnail is generated. Large videos can take a few minutes to process.

[09:26:42] Customer: It finished and plays correctly. Thumbnail appeared too.

[09:26:57] Support: Perfect. The issue was a combination of an outdated mobile app, a stale Wi-Fi restriction, and the reverse proxy’s upload-size limit. Your backup queue should continue automatically now.

[09:27:15] Customer: Yes, everything is uploading. Thanks for the help!

[09:27:24] Support: You’re welcome! Have a great day.
